The UC3825AN is a high speed Pulse Width Modulation (PWM) Controller, an improved versions of the standard UC3825 family. Performance enhancements have been made to several of the circuit blocks. Error amplifier gain bandwidth product is 12MHz, while input offset voltage is 2mV. Current limit threshold is assured to a tolerance of 5%. Oscillator discharge current is specified at 10mA for accurate dead time control. Frequency accuracy is improved to 6%. Startup supply current, typically 100µA, is ideal for off-line applications. The output drivers are redesigned to actively sink current during UVLO at no expense to the startup current specification. In addition each output is capable of 2A peak currents during transitions. Functional improvements have also been implemented in this family. The UC3825 shutdown comparator is now a high-speed overcurrent comparator with a threshold of 1.2V.

• Compatible with voltage-mode or current-mode control methods
• 50ns Propagation delay to output
• High-current dual totem pole outputs (2A peak)
• Trimmed oscillator discharge current
• Pulse-by-pulse current limiting comparator
• Latched overcurrent comparator with full cycle restart
• Green product and no Sb/Br
